What kind of problems did you have with your Gorilla tent? Were they there from the beginning? If not, how long before they showed up?
I've got a Gorilla Lite (2x4) and a Secret Jardin (3x3), and I like them both for different reason, haven't had any problems with either. In short; the SJ is easier to live with (easier zipper, more access to the top area), but the Gorilla has fewer light leaks, and is a bit more rugged construction all around.
